The result is malfunction of the hydraulic system and the operator has to change the servo valve. The electrostatic oil cleaner EFC D16 is able to remove the oxydation product, resin and varnish from the oil. The oil cleaned by electrostatic contains less varnish and is able to solve settled oxydation product and varnish from the surface of the hydraulic components.
The surface of the valves, of pumps, pistons and other hydraulic components becomes clean again. The movement of the different components is not blocked by the varnish and the hydraulic system will work more precise and without malfunction.
After the installation of the electrostatic oil cleaning system model D16 the hydraulic system of the aluminum press works now without hydraulic failure.
